Ok, makes sense. And a spider web with 3 routers comes next. You said I
should use the same IP for the cipe-devices as those of the
eth0s(?). The central router will have 2 cipe-devices and both need a IP and
the can not be the same, or am I mistaken? What IPs
should I give them then?
Would something like this make sense and would it be quite good maintanable?
| Router A eth0: 192.168.1.1
